Product Review: GE DPI 620 Genii

Now that we’re taking a break from level measurement, we can start chatting about other topics again, like multi-function devices. If we had all our field tools combined into a single device, we’d save time executing field tasks. You have a multimeter, a handheld, and a calibrator in your workshop, right? I used to carry these tools too, so I know you lose time organizing and maintaining all of them to keep a tidy workplace in the field.

Technology now lets us have tools with more than one function, which can save a lot of time and effort in setting up and monitoring field devices. Of course, this sort of tool costs more than a single-function device, but I believe it’s a good investment in the long term.

With that said, stand up and give a cheer to GE for bringing the DPI 620 Genii to the table! This portable multifunction calibrator may take us to the next level, so we’re gonna give you a complete overview of it.

Grab a currywurst, take a seat, have a read, and draw your conclusions!

Whatcha got there?

The answer to your prayers? Hmmm, maybe. The DPI 620 Genii is a calibrator, test meter, and field communicator. You can set up HART, Foundation Fieldbus (FF), and PROFIBUS devices using its tools. Furthermore, it can generate and measure pressure, temperature, frequency, and electrical signals. So far, so good!

The look of it appeals to me too. The compact design weighs less than 600 grams, and it has a lovely LCD color touch display designed with the user experience in mind, allowing gestures and swipes for navigation.

Furthermore, the electrical connections are clear and standard, making it easy to connect cables without even glancing at the manual. And if you want to communicate with a HART, FF, or PROFIBUS device, then the DPI 620 can provide loop power and communication; you don’t need an external power supply.

As for the calibrator, it has a modular system. That means you can add new functions – pressure modules, pressure generation stations, whatever – when you need them or skip them if you don’t, which helps in the financial department.

What can it do?

More than you can imagine! And I’m not kidding. Let’s start with the core functions. First, if you need to check the electrical supply or current output of your device, then the DPI 620 can read and generate up to 6 channels for various uses such as frequencies, RTDs, and thermocouples.

Now, if you need to communicate in the field with a level transmitter, then the DP1 620 can help with its HART, FF, and PROFIBUS protocols. Better yet, you get free updates for your database, which has been a handheld issue for years. Best of all, if you need to set up a device in the workshop, the DPI 620 and its cables will take care of your power supply and a bunch of other odds and ends!

And when you need to calibrate or diagnose field devices, you can generate and read pressure, temperature, and the other electrical signals. You might need to add a module to get exactly the feature you need, but that’s one of the benefits, right? You don’t pay for what you don’t need.

Why should I care?

Because the DPI 620 can take care of nearly all of your process needs and fits in your pocket! However, we have more reasons why you should care about this tool, so let’s see if any apply to you. We already mentioned the long list of features, but there are more fancy things as well.

The Analysis feature lets you compare a reference with a field device. You can set up a channel as a reference and compare this channel with another. Then, the 620 will calculate the difference between the channels and show the deviation in %span or %range, with the result as “pass” or “fail.”

And a lot of calibration procedures are similar, right? Well, you don’t need to do the same procedure manually again and again. You can use the Run Procedure feature and set up the procedure you need for your transmitter. Depending on the software, you can download it directly to use the same procedure.

What about intermittent problems? Maybe you want to monitor the device for a while. You can use the DPI as a data logger on the device to review and analyze the information afterward. Sounds good, huh?

Furthermore, the DPI 620 has certification for hazardous areas, a battery that promises 12 continuous hours of juice, an internal memory of 4 GB, and a 8 GB microSD card! Not bad at all.


We need more of these things. Thanks, GE, for offering a good start on our road to the future.
